We have developed our custom product in which we have been used the "LT3476EUHF" led-driver IC to control four illumination(RED,BLUE,GREEN.IR) LEDs of camera flash.
Now we are trying to control the individual led but as per our analysis driver is does not work properly.
We fixed the all 4-PWM to 60 micro-second ON-time and 40 micro-second OFF time and we are controlling the "Vadj1-4" using DAC IC where we had set range to 500mv.
Now the individual and four LEDs are working good (not proper) but does not work twice or thrice at time so we need support to solve this issue as soon as posible.
Thanks & Best Regards,
